Power Automate "Get Items" doesn't list calendars

[EHollandbeck]

I have a couple of event calendars on our site that I want to set up reminders 30 days in advance of an event. When I use Get Items, I can only select Lists. My calendars were not built from a List. How do I create a reminder flow for Event Calendars?

You need to write the name of the calendar manually. The dropdown till only show regular lists
